- Abstract
Objective: To evaluate the peri-operative, functional and oncological outcomes of robot-assisted partial nephrectomy (RAPN) and laparoscopic partial nephrectomy (LPN) for moderately or highly complex tumours (defined as RENAL nephrometry score ≥7). Patients and Methods: We retrospectively analysed the medical charts of 216 patients with complex tumours who underwent LPN (n = 135) or RAPN (n = 81) between 2008 and 2014. Peri-operative data, pathological variables, complications, functional and oncological outcomes were reviewed. Results: Demographic characteristics were similar in the two groups. LPN was associated with a longer operating time (149.6 vs 135.6 min; P = 0.017) and greater estimated blood loss (220.8 vs 196.5 mL; P = 0.013). RAPN was associated with a higher direct cost. There were no differences in warm ischaemia time, transfusion rate, conversion rate, hospital stay, operative complications and estimated glomerular filtration rate change at 6 months after surgery. The mean follow-ups for LPN and RAPN were 31.4 and 16.5 months, respectively. The 3-year recurrence-free survival rate was 95.2% for LPN and 97.1% for RAPN (P = 0.71). Conclusion: In patients with complex tumours, RAPN and LPN provided acceptable and similar results in terms of peri-operative, functional and oncological outcomes. RAPN was superior to LPN in terms of estimated blood loss and operating time, and LPN was the more cost-effective approach. Both surgery techniques remain viable options in the management of complex tumours with RENAL scores ≥7.
